  • Publication number: 20250086004
    Abstract: A computer-implemented method includes determining a quantity of reserved resources that need to be reserved in one node. Nodes in which quantities of current remaining resources are less than a quantity of reserved resources are determined. For each determined node, calculating a total quantity of resources occupied by allocated service requests in the node and determining whether the node is capable of satisfying the quantity of reserved resources. If yes, marking the node as a migratable node. One migrating node is selected from migratable nodes and corresponding M allocated service requests are migrated to at least one other node. Resources occupied by the M allocated service requests are released, where M satisfies a condition that after the resources occupied by the M allocated service requests are released, a quantity of remaining resources in the migrating node is not less than the quantity of reserved resources.

  • Patent number: 12244479
    Abstract: An anomalous behavior detector has been designed to detect novel behavioral changes of devices based on network traffic data that likely correlate to anomalous behaviors. The anomalous behavior detector uses the local outlier factor (LOF) algorithm with novelty detection. After initial semi-supervised training with a single class training dataset representing stable device behaviors, the obtained model continues learning frontiers that delimit subspaces of inlier observations with live network traffic data. Instead of traffic variables being used as features, the features that form feature vectors are similarities of network traffic variable values across time intervals. A feature vector for the anomalous behavior detector represents stability or similarity of network traffic variables that have been chosen as device identifiers and behavioral indicators.
